Specification of Letters Patent. Application filed December 30, 1908.Serial No. 470,094.

To all whom it may-concern: l

Be'it known'that 1,.TILLIAM PHILIP SMITH, a citizen of the UnitedStates, and a resident of El'Paso, in the county of El Paso and State ofTexas, have invented a new and Improved Signaling Device, of which thefollowing .is a full, clear, and exact description. t

This invention relates tosignaling devices for use on engines, railroador trolley cars. The object of the invention is to provide an improveddevice which may be operated from the cab of an engineer by the operatorof a car.

In its present'embodiment, itcomprises a plurality 'of levers rranged todisplay signals or be housed wi hina, asing, and mechanism whereby thelevers ay be locked in either position,- and also means for locking theoperating mechanism, Said loekin or other locality occupied by theoperator;

The invention consists in the construction and'co'mbination of parts, t9be more fully described hereinafter and particularly set forth intheclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis spec'ifi cation, in which similar characters of reference indicatecorresponding parts in all the views, and in which,

Fi re 1 is a perspective view, showing the evice applied to a locomotiveboiler;

' Fig. 2is a front elevation, dpartly insection,

showing the device applie to aboiler, and

. having additional signals displayed; Fig. 3

is a horizontal section, taken on the line 3-3 in Fig. 2; Fig. 4 is anenlarged detail view, in sectlon, of the mechanism for lock-y P g ing te levers agalnst movement; and Fig. 5 is a detail view, on an enlargedscale, showing the means for locking the operating mechanism.

'As at present shown, the mechanlsm 1S arranged to display four greensignals, 1,2, 5

and 6, and two white signals, 3 and 4. It is to be understood that thenumber and colors of the signals may be varied to suit variousrequirements.

Although the mechanism is shown mount-= ed upon the front endof alocomotive boiler,

it will be understood'that said mechanism may be mounted upon'a car orinany other the spirit of the invention. Y

The signal may comprise a disk mounted suitable locality, withoutdeparting from Y I larto the rodlO.

upon one end of a lever 8. Said lever is pivoted about a rod 10 mountedin a bracket 12 which is secured to the outside of the boiler 14 of theengine. The lower end 15 of the lever 8 is pivotally connected-to oneend of a link 16. The other end of the link 16 is pivotally connected tothe upper end 17 of a lever 18. Said lever is pivoted about a rod 19,which may be supported at its ends in a casing or housing 20.- The lowerend of the lever 18 is pivotally connected to one end of a link 22. Theother end of the link 22 is pivotally connected to one arm 24 of abell-crank lever 25. Said bell-crank lever is pivoted about a verticalstud 26 mounted in lugs 27 extending laterally from a bracket 28, whichis bolted to the outside of theboiler 14.' The arm 30 of the bellcranklever 25 is connected to a rod or other operating instrumentality 31,which extends to the cab of the engine.

The signal 3 comprises a on one end of a lever 34, also pivoted aboutthe rod 10. The other end of the lever 34 is pivotally connected. to oneend of a link 35, the other end of which is pivotally connected tothe'upper end 36 of a lever 37 which is also pivoted about the rod 19;The lower end of the lever 37 is pivotally connected to one end of alink 38, the other end of which is pivotally connected to one arm 39 ofa bell-crank 40, which is also pivoted about the stud 26. The arm 42 ofthe bellcrank lever 40 is connected to a rod or other instrumentality 44also extending to the cab of the engine.

The signal 5 comprises a disk secured to one end'of a lever 45 pivotedabout the rod 10. Said signal 5 and also the signal 6 are markers, whichare used when the engine is to be backed up. As these signals are seldomdisplayed as compared with the signals intended to be operated by theengineer, they may be operated by hand from the front of the eng1ne.. 1

The signal 2 comprises a disk mounted upon one end of a lever 48,pivoted about a 'rod49's'uitablysugported in a manner simihe lower endof the lever 48 i's pivotally connected to one end "of 'a link50,-:which has its other end pivoted to the 1ever 18..; p

r The signal 4 comprises a disk mounted on one end of a'lever 52, whichis also pivoted disk mountecb aboutthe rod 49. 1 The other end of thelever 50is pivotally connected to oneend of a link 54, having its otherend pivotally connected to the lever 37.

In order to support-the signal levers when displaying the signals, aseries of yokes 58, 59 and 60 are secured together and mounted 'upon anupwardly-projecting arm 61 of thebracket 12. A locking bolt 64 isslidably mounted in the arms. 61 and 65 of .the bracket 12 and extendsthrough the yokes 58, 59 and 60 above the point where the levers arefulcrumed about the rod 10. Said bolt 64 is provided with a collar 66and a coiled spring 67 surrounding said bolt and I extending between thecollar 66 and the arm 65 on the bracket 12 A similar set of yokes '70,71 and 72 are secured together and mounted upon one arm 73 of a bracket74 fastened upon the boiler 14. A locking bolt 75 is mounted to slide inthe bracket 74, and

extends through the yokes above the rod 49 in a manner similar to thatof the locking bolt 64.

The casin or housing 20 is provided with bolts 78 and 80, which extendthrough the same and connect both sides thereof, to formsupports for thelevers of the signals which are obscured from view. Said casing may alsobe utilized to display the number plate of the engine. Said casing alsoprotects the signals from the heat of the boiler and from rain and dirt.Said casing is suitably supported from the front of the boiler by ro s81 and 82.

A rod 85 is journaled in bearings 86 and 87 formed upon brackets 88 and89 respectively, which are bolted to the upper side of the boiler 14.Sleeves 90 are secured to the rod 85 and provided with cars 91, to whichthe upper ends of springs 92 may be fastened. The lowerends of saidsprings are secured to the boiler. An arm 94 is secured to one end ofthe shaft 85 and spans the looking bolt 75 at its lower end. Said arm 94is arranged to engage a collar on the-locking bolt 75 similar to thecollar 66 on the locking V bolt 64. An arm 96 is secured to the otherend of the shaft 85, and has its lower end spanning the locking bolt 64and engaging the collar 66. Asleev e 98 is secured to the arm 96. A link99 is pivotally connected at one end to the sleeve 98 and at its otherend to the upper end 100 of a lever 101, fulcrumed about apin 102mounted upon "the of the bell-crank lever 25.

on a bracket end with a depending projection 114, which is adapted tolie in the path of the arm 24 The free end of the spring-arm 109 isprovided with an upwardly-extending projection 115, which is adapted tolie in the path of the arm 39 of the bell-crank lever 40. When the cam106 is turned so that the spring-arms 108 and 109 assume the dotted-lineposition shown in Fig. 5, the hell-crank levers 25 and 40 are 3 free tobe moved -by theiroperating connections 31 and 44. Until thesespring-arms are thus moved, said bell-cranks cannot be moved to operatethe signals. The junction of the lower end of the lever 101 with thelink 105 is connected to a yoke 120,'which is also connected to a rod121 extending to the cab of the engine. i

The operation of the device is as follows: In order to operate thesignals, the rod 121 is pushed forward, so that the joint between thelever 101 and the link 105 may assume the dotted-line osition shown inSimultaneously t erewith the upper on of said lever 101 is moved towardthe left, as vinwed in Fig. 1, thereby drawing the arms 94 and 96 in thesame direction, which act u on the collars which are mounted upon theocking bolts 75 and 64 respectively. This frees any signals which may besupported in the yokes 58, 59, and 71, but if the signals are all housedwithin the casing, it prepares the yokes to receive the signs. 5. At thesame time the cam 106 forces the spring arms 108 and 109 apart, so thattheir projections 114 and 115 are moved out of the paths of thebell-crank levers 25 and 40. Thereupon the rods or connections 31 and 44may be operated from the cab in order to. move the signals as desired.when the signals have been moved, the rod 121 is drawn toward the left,as viewed in F' 1, thereby movin 105 into the fa l-line position shownin Fig. 5. Under the action of the springs 92 and the springs 67and 74,the mechanism for moving the locking bolts and 64 is :(per ated. Thesesprings may be so design as to automatically restore the lockingmechanism as soon as the rod 121 is-released from the hands of theoperator after the signals have been 0 erated.

Having t as described my, invention, I
